Abstract

전자 사진용 감광성 부재는 전도성 지지체 위에 보호층과 감광층을 순차적으로 배치시킴으로써 구성된다. 이 보호층은 전도성 입자, 불소계 수지 입자 및 결합제 수지를 함유하는 것을 특징으로 한다. 보호층은 고 감광도 및 저잔류 전위와 같은 우수한 전자 사진 특성을 나타내는 전자 사진 장치를 제공하는데 적합하고, 또한 임의의 환경 조건하에서 양호한 화상 형성 특성과, 개선된 피즈 메모리 특성 및 감소된 전자 메모리를 제공하는데에도 적합하다.The electrophotographic photosensitive member is constructed by sequentially placing a protective layer and a photosensitive layer on a conductive support. This protective layer is characterized by containing conductive particles, fluorine resin particles and binder resin. The protective layer is suitable for providing an electrophotographic apparatus exhibiting excellent electrophotographic characteristics such as high photosensitivity and low residual potential, and also provides good image forming characteristics under any environmental conditions, improved pep memory characteristics and reduced electronic memory.
